POLYLACTIC ACID-BASED RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To obtain a polylactic acid-based resin composition having excellent heat resistance and impact property and a molding that is composed of the resin composition and has excellent heat resistance. SOLUTION: The polylactic acid-based resin composition comprises a polylactic acid-based resin and a thermoplastic norbornene-based resin having≥110°C deflection temperature under load (0.45 MPa load). The polylactic acid-based resin composition comprising an ethylene-unsaturated carboxylic acid copolymer and/or its ionomer is prepared and a molding is obtained from the resin composition.
